TEL AVIV, Israel — As the Israeli Air Force continues to investigate the Feb. 10 loss of an F-16I to Syrian anti-aircraft fire, experts here are privately questioning why, given the operational circumstances that denied Israel the element of strategic surprise, it did not opt to deploy its newest front-line fighter: the stealthy F-35I.

In early December, the Air Force declared initial operational capability of the nine F-35s now in its possession. And from the aerial activity reported by residents near its home base at Nevatim, southern Israel, the aircraft are accruing significant flight time.

Yet none of the operational F-35s were part of the eight-aircraft force package tasked with destroying an Iranian command center in central Syria. The command center was reportedly operating the unmanned Shahed 171 drone that Israel says penetrated its airspace in the early morning of Feb. 10.

Nor were they tasked to lead the follow-on wave of strikes on 12 separate Syrian and Iranian assets in the punitive operation launched later that day in response to the F-16I downing.
But why not?

Perhaps these costly stealth fighters are too precious to use. Or perhaps the Israeli Air Force is not sufficiently confident in the aircraft or its pilots’ proficiency in operating the fifth-generation fighter.

Given pledges by Syria and its Hezbollah allies of “more surprises” should Israel venture additional attacks on Syrian soil, will the Israel Air Force opt to use these front-line assets next time around?

The official answer to all these questions, according to Israel Defense Forces spokesman Lt. Col. Jonathan Conricus, is: “No comment.”
